Narrated Abu Said:

A woman came to Allah's Apostle and said, "O Allah's Apostle! Men (only) benefit by your teachings, so please devote to us from (some of) your time, a day on which we may come to you so that you may teach us of what Allah has taught you." Allah's Apostle ﷺ said, "Gather on such-and-such a day at such-and-such a place." They gathered and Allah's Apostle came to them and taught them of what Allah had taught him. He then said, "No woman among you who has lost her three children (died) but that they will screen her from the Fire." A woman among them said, "O Allah's Apostle! If she lost two children?" She repeated her question twice, whereupon the Prophet ﷺ said, "Even two, even two, even two!" (See Hadith No. 341, Vol. 2)

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الأَصْبَهَانِيِّ، عَنْ أَبِي صَالِحٍ، ذَكْوَانَ عَنْ أَبِي سَعِيدٍ، جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ ذَهَبَ الرِّجَالُ بِحَدِيثِكَ، فَاجْعَلْ لَنَا مِنْ نَفْسِكَ، يَوْمًا نَأْتِيكَ فِيهِ تُعَلِّمُنَا مِمَّا عَلَّمَكَ اللَّهُ. فَقَالَ " اجْتَمِعْنَ فِي يَوْمِ كَذَا وَكَذَا فِي مَكَانِ كَذَا وَكَذَا ". فَاجْتَمَعْنَ فَأَتَاهُنَّ رَسُولُ اللَّهِ ﷺ فَعَلَّمَهُنَّ مِمَّا عَلَّمَهُ اللَّهُ ثُمَّ قَالَ " مَا مِنْكُنَّ امْرَأَةٌ تُقَدِّمُ بَيْنَ يَدَيْهَا مِنْ وَلَدِهَا ثَلاَثَةً، إِلاَّ كَانَ لَهَا حِجَابًا مِنَ النَّارِ ". فَقَالَتِ امْرَأَةٌ مِنْهُنَّ يَا رَسُولَ اللَّهِ اثْنَيْنِ قَالَ فَأَعَادَتْهَا مَرَّتَيْنِ ثُمَّ قَالَ " وَاثْنَيْنِ وَاثْنَيْنِ وَاثْنَيْنِ ".
